Reaction Steps

26 g of acetoacetic acid ethyl ester were dissolved in 20 ml of absolute ethanol. 30.0 g of α-methyl-4-methylbenzylhydrazine in a little absolute ethanol were slowly added to this solution under nitrogen. After the exothermic reaction had subsided, the mixture was heated for 2 hours under reflux. On cooling, the crude product crystallized out and was purified by recrystallization from methanol. Melting point 144°-146° C; yield 28 g (65% of theory).
